Be it known that we, J UDsoN L. THOMSON and J ABOB J. UNBEHEND, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Rivet-Slotting Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

slotting machine, and has for its object the production of a simple and effective device which shall continuously and automatically feed the rivets or like artic es to a cutter or or bifurcated to allow of their ready insertion when used, and the ready clinching or bending over of the bifurcated shank when the rivet is in the desired position.

shaft to which is secured a cutter or breach, a feeder for continuously and automatically feeding the rivets to thecutter or broach, a die or other means for holdingthe same dura discharge for discharging the rivet from the die into a suitable receptacle adjacent thereto after the shank of the rivet has been bifurcated by the broach.

Unbehend, of even date herewith; but for the purpose of specifying our present invention it is unnecessary to describe the detail construction and arrangement of the hopper whereby the rivets are fed, as previously stated, except to say that it is suitably connected to the'actuating mechanism'of the machine.

When, as illustrated, a hopper is used which feeds the rivets shank downward, it will be observed from the peculiar construction and arrangement of our device that the conveyer G must be twisted in order that the rivet shall be shank downward when discharged into the receiver K, while when a hopper is used which discharges the rivets therefrom with their shank upward there'is no necessity for twisting the conveyer G. The rivet is conducted from the hopper B to the re.-- ceiver K by the conveyer G, which discharges the same from the end g intothe receiver in. 12, supported the position illustrated in Fig. by yielding or spring-actuated shoulders K ceiver K is the plunger-rod P, mounted on the plunger P, adjustable thereto, preferably with its upper end threaded and engaging like threads in the plunger P and secured theretoby the set-screw 1). Provided on a bracket a, mounted upon the main frame A, is the guideway a through which reciprocates the plunger P, provided with a slot 10, in which is mounted the rounded end E of a lever or walking-beam E, having the pivotal pins e secured thereto and journaled in the bracket a. The opposite rounded extremity E of this lever is mounted in a like slot fin a plunger F, reciprocating in a guide- I way a also secured to said bracket a.

The lower end'F of the sliding-rod F is provided with a roller f, which by means of aspring e suitably connected to the pivoted lever E, is constantly contacted with a cam Fimounted upon the shaft F to which mo- "tion is conveyed by suitable gearing F connected to the driving-pulley F actuated by When the shaft F is rotated, the cam-tooth F 'of the cam F contacts with the roller f,forcing the sliding rodF upward, elevating the extremity E of the pivoted lever E and depressingthe extremity E of said lever, thus forcing the plunger-rod P through the receiver upon the rivet previously inserted by the conveyer G.

der. h blocking Guided through the re- For the purpose of inserting the rivets one by one at the desired time into the receiver K we interpose in the conveyer G a cut-off illustrated in Fig. 15, and described and claimed in the application of Jacob J. Unbehend, (Case A,) of even date herewith. It will be seen by reference to Fig. 15 that the feeding-slot g is set oif on either side of the cutoff G, and that lugs G are interposed in the conveyer G in a slot G provided therein. The cut-off G is actuated by a rod H, supported in a standard it, secured upon the main frame A. Provided upon said sliding rod H are shoulders h h between which shoulders we provide the spring-rod 1', supported in the pivoted lever I, secured by a set-screw t" to the pivot e of the lever .E. Thus it will be seen that as the pivotal leverE is rockedand plunger-rod P through the receiver K the lever I, secured by the set-screw ito the pivot e of said pivoted lever E, is also rocked, and the spring-rod t' contacts with the rear shoulthe discharge of the rivets into the receiver and registering the slot G between the shoulders G of the cut-off with the slot in the upper part of the conveyer G, allowing the entrance of a rivet between said shoulders." When, after the passage of the cam-tooth F, the said lever is retracted with its end E forced downward by means of the spring 6 lever I is again rocked and the rod 1' secured thereto contacts with the forward shoulder 71 secured upon the rod H, blocking thefurther feeding of the rivets into the cut-0E, and registering the rivet now in the slot G with the slot 9 of the discharge end g of the conveyer, down which slot the rivet slides, and is thereby conducted into the receiver immediately upon the withdrawal of the plunger. Thus it will be seen that when the plungerrod is discharging a rivet from the receiver the rivets in the upper part of the conveyer are blocked from entrance into said receiver, and that immediately upon the withdrawal of the plunger at every operation thereof the cut-off is actuated to feed a single rivet down the discharge end '9 of the conveyer G, thus automatically feeding the rivets one. by one to the receiver K previous to every operation of the plunger.

Directly beneath the discharge is of the receiver K is the holder or die L, secured to 85 its forward extremity E forces downward the secured to said lever, the pivoted the'frame A by the plates L, and provided with an aperture Z, into which the rivet is inserted by the plunger-rod P, which securely holds the rivet in the aperture Z during the operation of the cutter in bifurcating the rivet-shank, as shown in Fig. 10.

In order to readily discharge the rivets-from the die L, we provide the discharge mechanism presently described, and, asshown in Fig.

9, we support the discharge end In of the receiver considerablyabove the die L, thus allowing of the operation of the discharge v mechanism.

k in the discharge end 7s rivet to be easily out without much for ofv said broach. side of the breach U, bevels the outer face of The receiver K is provided with an extending arm K mounted upon a'rod K secured in hubs K, provided upon a supportingbracket K secured to the bracket a. After a rivet has been inserted into the receiver K it is caught by the spring-shoulders K, and when the plunger-rod P is forced downward by its actuating mechanism, as previously described, the spring-shoulders K are forced apart, and the rivet is drivendown until its head is contacted with the shoulders or jaws of the receiver. WVhen the rivethead is contacted with said shoulders k the receiver is forced downward upon its guide-rod K against the action of the spring K, retaining the same in its nor 'mal position, thus approximating the rivet to the die L. After the receiver has reached the limit of its motion, by reason of the contact of the lower face of the extension K with the lower hub K of the supporting-bracket K the separate sides is of the receiver, formed by a vertical slot or slit extending upwardly from the discharge 7e, are forced apart, allowing the passage of the rivet-head and the plunger-rod P.

Directly'beneath the die L is the cutter U, which is actuated to bifurcate the shank of the rivet while the same is being held in the die by means of the plunger-rod P, as shown in Fig. 10. The cutter U consists of a broach U, interposed between two -like collars U mounted on the shaft F and secured thereto by means of the nut W, impinging said collars against a shoulder f, provided upon said shaft,.and shown in dotted lines in Fig. 6. The broach U is secured to these collars U by dowel-pins u, and is preferably cam-shaped or eccentrical to said collars U being formed with the cutting extremities of its teeth projecting one beyond the other and movable in planes one beyond the other, whereby its forward end only takes a small cut out of the rivet, and as the broach is rotated the out is deepened until the rear end of the broach is reached, when the cut is of sufficient depth. By this peculiar form of cutter I enable the strain upon either the rivet or the broach.

On either side of the broach for bifurcating the rivet we provide the cutter V, mounted in a slot U provided, preferably, in thecen- The cutter V, on the outthe bifurcated extremities of the rivet-shah k, and is secured to the broach by means of setscrews 1;, bearing upon said cutter. In order to allow the broach U and cutter V to operate upon the rivet, it is necessary to provide slots Z Z in the bottom face of the die, as illustrated in Figs. 7 and 8.

Mounted upon the frame A are brackets T, secured to said frame by bolts t or other suitable means, and carrying-brushes if, the forward ends of which brushes are held in the path of the rotating cutter and serve to clean passing through the collars U and tion of its spring 0.

Mounted upon a cross-shaft J secured in suitable bearingsJ an arm J, carrying at its forward a fork J, normally lying on either side of the rib Z formed bythe cut-out Z on thetop face of the die L. WVhen the rivet the die L by the action of the plunger-rod P and the receiver K, the head of the rivet will rest upon shoulders j on either side of the openingj'of saidfork. After the breach has bifurcated the rivet, a cam the shaft F contacts with a pivoted lever M, secured to the shaft J by the set-screw m, forcing upward the free extremity of said lever M, rocking the shaft J and elevating the fork J, secured on the free extremity of the pivoted lever J, ward and out of engagement with the die by reason of the engagement of the rivet-head with the shoulders j of the fork, as illustrated in Fig. 11 of the drawings. A discharge-fin ger N is normally held above the fork J, with a depending projection N, held over the open ingj of the fork and just back of the rivet head. This finger is secured at one extremity to a sliding bar it, arranged transversely of the frame This sliding rod n is guided in ways 72, secured to the main frame A. A spring 0, secured at oneextremit-y to the sliding bar at and at its opposite extremity to a, post 0, rigidly securedto the table, retains this bar in its normal position with the depending proj ection N of the discharge-finger N just back of the rivet-head.

Pivoted in the arm w -is the lever wflprojecting over the slotg of: the conveyer G, with its inner edge sufficiently removed from said slot to allow the passage of rivets of the desired size to be operated in1our machine. If a rivet larger than desired should be fed down the conveyer-G, it will be seen that the broach U would be unduly strained when cutting the same, and there would be a liability of breaks ing the die orinjurin g the broach. By means of this stop-:w we prevent the passage to said breach of any rivet the shank of which is longer than the regular rivet, thus stopping the further feeding of the same until the rivet is removed. On the oppositearm 20 of the platew we hinge a rod or barwfiwhich is nor mally swungout,as illustrated in'Fig. it, but

whichwhen it is desired tostopthe feeding of the rivets is swung intothe position illustrated by dotted'lines in said figure, effectually stopping "the feedingof the rivets until the withdrawal of said arms Upon reference to the drawin gs andtheforeoingdescription it will be" readily understood that the the=conveyer G, thereceiver K, and'the plunand we so relatively ar-' rivet for the purposemounted therein and in: alignment with the sliding rod-n, allowing the movement of the sliding rod n to be adjustbracketrK we provide the plate feeder consists ofthe hopper B,

ger P, that the holder consists of the die 'L,

and the discharge of the finger N.

The operationof our machine is as follows: The rivets'are forced into the conveyer by the hopper, the cut-off feeds a single rivet down the discharge end of the conveyer into the receiver, the plunger forces the rivet through the receiver into the die, the rivet-shank, the fork elevates the rivet out of engagement with the die, and the dischargefinger discharges the rivet from the fork into a suitable receptacle adjacent to said'fork.

It will be understood that considerable change may be made in the relative constructhe cutter bifurcates {tion'and arrangement of the various parts of 1 our machine, and that other constructions may be used for feeding the rivets to the die" and for discharging the same therefrom; hence we do not limit ourselves to the'precise form and construction ofthe difierent parts of our improved rivet-slotting machine. i Having thus fully described our invention,
